Stage 1 Vs. Stage 2 Gen 6 3.0 L Superchargers

The launch of the S650 platform ushered in a new era of Mustang performance. For enthusiasts looking for reliable, record-breaking power, the VMP Performance Gen 6 supercharger upgrade is an easy button for performance.

The VMP Gen 6 3.0 L Supercharger kit has been designed to overcome the complexities of the Mustang’s dual-inlet design, delivering serious power gains while retaining factory-level drivability. But the question quickly becomes: Stage 1 or Stage 2 – which one is best for your build? We installed our Stage 1 and Stage 2 packages on a pair of 2024 Mustang Dark Horse models and ran them on our dyno to help you decide.

Note: While our dyno figures are representative of the gains you can expect, the exact numbers you pull will vary depending on your vehicle type, contributing mods, and the running environment.

Stage 1: Reliability Meets Performance

The 2024 Mustang Dark Horse already produces 500 hp stock, but once you account for drivetrain losses and measure power at the wheels, it puts out a slightly lower 413 hp. Still impressive, but our Stage 1 Kit is a perfect performance-enhancing solution designed for the modder who wants a significant power boost without sacrificing daily drivability or peace of mind:

• Power Improvement: Increases power from 413 rwhp to 701 rwhp.
• Torque Improvement: Pushes torque from 377 lb-ft to 591 lb-ft with a flat curve for immediate throttle response.
• Kit Highlights: 92 mm GT500 throttle body, 3.875 in pulley, upgraded air filters, and Stage 1 specific calibration.

The VMP Gen 6 3.0 L Supercharger Stage 1 Kit utilizes a 92 mm round throttle body sourced from the Shelby GT500, ensuring OEM-level reliability and smooth tuning. This stage is particularly attractive to those seeking factory-like security, and an optional powertrain warranty is available with this kit for a separate fee.

While the Stage 1 kit features a slightly more conservative rev limit of 7,500 rpm, it transforms the Mustang into a true 700+ horsepower machine. And that’s rear-wheel horsepower, which translates to well over 800-hp when measured at the crank.

Stage 2: Unleashing the Beast

For those demanding maximum performance, the Stage 2 Kit pushes the 3.0 L head unit to its full potential. The defining difference is the massive 112 mm billet round single-blade throttle body and a smaller 3.75in pulley. These components allow the supercharger to breathe more freely and generate roughly one additional pound of boost.

• Power Improvement: Increases power from 413 rwhp to 761 rwhp.
• Torque Improvement: Peak torque goes from 377 lb-ft to 586 lb-ft.
• Kit Highlights: 112 mm Billet throttle body, 3.75 in pulley, and high-rpm aggressive calibration.

The Stage 2 calibration is more aggressive, moving the rev limiter to 7,800 rpm. This allows for a staggering 760+ rear-wheel horsepower output and superior high-end pull. It also offers the best bang-for-your-buck value as the price difference over the Stage 1 kit is less than $1k.

Choosing the Right Path for Your S650

Deciding which supercharger kit to go with depends on your ultimate goals for the build. If you use your Mustang as a high-performance daily driver and want the added peace of mind of a warranty, Stage 1 is the go-to choice. It offers incredible gains that will make every drive an event to remember.

On the other hand, if you are chasing track times, Stage 2 is the clear winner. The larger throttle body ensures the supercharger never runs out of air, even at the 7,800 rpm redline. It offers stock-like drivability, and performance gains are even more impressive.
